How to Disable Hibernation on Windows 10 Laptop and Desktop?

When the PC hibernates, it takes a snapshot of the Windows kernel and drivers. The snapshot is being saved to the HDD or SSD of your computer.

Sleep, Hibernation, and Hybrid Sleep. What is the Difference?

Sleep and hibernate modes on Windows 10 are different:

  • Sleep mode is a power-saving mode (similar to pause playback in any media player). Files and running applications are saved in RAM.
  • In hibernation mode, the computer is turned off and does not consume power. Hibernation is primarily intended for laptops.
  • Hybrid Sleep mode combines sleep and hibernation. This mode is intended for desktop PCs. Opened files and applications are saved in memory and on HDD or SSD. You can quickly wake up your computer.

Disable Hibernation to Free Up Disk Space

Waking the computer from hibernation is faster than turning it on. The hibernation file size is 75 percent of your computer’s RAM. If the computer has 8 GB of RAM, the size of the hiberfil.sys is 6 GB.

The hiberfil.sys file is located in the root directory of the system drive C: \. It is impossible to transfer the hibernation file to another drive since the kernel loader can only see the disk partition where the loader is installed.

The command not only disables hibernation but also deletes the hiberfil.sys file. This can free up some space for your apps and files.

If you disable the hibernation, you won’t be able to use the quick start function of the computer either.
